I made a video to describe a lower body move that most people avoid because they have been hit over the head so many times about not sliding and staying behind the ball.

You are supposed to keep your upper body behind the ball, while your lower body moves toward the target and gets your weight to your front side. That also causes the ideal spine tilt behind the ball if your upper body is behind the ball and lower body moving toward the target.

For some there will be a small amount of rolling on the outside of the front foot, even though it is not ideal. What you don’t want is a significant amount of roll on the outside of the front foot.
